Application of Ultrafine Fly Ash in Commercial Concrete

Abstract:

Application of ultrafine fly ash grinded by low quality fly ash in commercial concrete was studied, and the studied content included fineness test, mortar strength, concrete strength, admixtures adaptability, impermeability and dry shrinkage. Results show that ultrafine fly ash grinded by low quality fly ash had a very good activity and admixtures adaptability, can greatly improve the strength and impermeability of concrete, and reduce dry shrinkage, and has good applicability in commercial concrete.
